To Get In

To get to Baguio from outside of Luzon, one would still need to pass through Manila or Clark airport and from there get to Baguio by either of the following ways
From Manila
This is the most common and economical way to get to Baguio from Metro Manila. Several bus lines ply the Metro Manila to Baguio route with terminals scattered across the metro. It generally takes about 5 hours to get to Baguio by bus. An hour longer than it would by car due to stopovers along the way.

Victory Liner
Has hourly bus service to Baguio from its Cubao (+632 727-4534) and Pasay (+632 833-5019 to 20) terminals. Buses are generally modern and air-conditioned but seats are sized generally for Filipinos and tall people would need to take advantage of the various stopovers to stretch their legs. Cost is just under 400 Pesos per person one way.
Dagupan Bus, Edsa cor. New York St., Cubao, Quezon City, Tel. +632 929-6123, 928-5639, 727-2330, 727-2287. Also serves the Manila to Baguio route via its Cubao Terminal. Buses leave on an hourly basis.
From Clark airport
Partas Bus operates a bus service that stops at Clark airport and heads north from there, departing the airport at 5:00 PM. Get off at Sison (arrival there around 8:00 PM) and cross the road to the restaurant stop opposite and get on a Victory Liner bus that does a dinner stop there. The fare from Clark airport to Sison on Partas Bus is 193 pesos, then from there by Victory Liner to Baguio is an additional 90 pesos. Travel time is 3 hours Clark to Sison, then 1 1/2 hours Sison to Baguio, plus some waiting time at Sison.
By air.

Asian Spirit
As of June 2007 flies Sunday, Monday, Wednesday and Friday from Manila to Baguio. The flight takes only 50 minutes and lands in Loakan Airport which is about a 20 minute ride south of the city center. A return ticket costs 6,000 pesos.
By car
The only motorway from Manila to the south to get to Baguio via car is using the North Luzon Expressway which extends until Sta. Ines, Pampanga and there is no more motorway beyond this, only narrow roads such as the McArthur Highway. Visitors need to pass through the provinces of Pampanga, Tarlac and Pangasinan to get to Baguio quickly from Manila and the south. As much as driving is not advised for tourists in Manila, it is doubly risky to do it going to Baguio. There are three main routes leading up to Baguio by road, Kennon Road is the shortest taking only 30-45 minutes to climb from the foot of the mountain, Marcos Highway takes upto 1 hour to climb and Naguillan Road is 3 hours longer. All three roads can get blocked by landslides and Kennon Road with its long winding stretches is both scenic and dangerous. If you are intent on driving to Baguio, it would be best to hire a Filipino driver for this purpose. Most rental car companies in the Philippines offer chauffeur driven rentals in addition to the usual self-driven rentals.
Visitors need to keep in mind that it while it takes at average 6-7 hours to get to Baguio by car, it takes much longer during holiday weekends like Holy Week.
By jeepney
Similar to Manila, jeepneys ply various routes within Baguio and its immediate surroundings.

By taxi
More convenient for tourists perhaps, taxis are also common but once you are in the outskirts may be a bit hard to come by.
Taxis can also be booked for a whole day tour at 1,800-2,000 pesos for a 8-9 hour tour of all the main attractions in and around town. Find a taxi at the Tourist Information Counter at the Victory Liner terminal or through your place of accommodation.
